Thank you, thank you!

I don't know, but I don't know a thing about them - well, except that I
can dig out a specific test case from certain open-source OS kernels,
which auto-detect it at boot time.

It's not classes that I learnt this stuff from.  It's from hacking
around with it for umpty-ump years.  (For example, I once did a PDP-11
emulator that did floating point, and getting the floating point right
without depending on the host's floating-point implementation demanded
a fair bit of research and thought.)
